Fig. 1

Gene expression network modeling in [ER+] and [ER-] samples. Graphs were designed by computing nonlinear correlation and mutual information between each gene expression pair in either ER-positive (a) or ER-negative (b) samples. The vertices represent genes. The edges linking the vertices indicate that independence between gene expressions is less than 0.05 and links for ERα36 are in bold. P-values are given in Additional file 1: Table S1A and Additional file 2: Table S1B, respectively
